The Big Gold lies south of Teuton’s Orion property and west of the Four J’s. Recent meltback of snow and ice has exposed a large area of gossanous, northerly trending zones as shown in the photographs below. Very limited prospecting carried out in 2015 has shown that some of the zones are highly anomalous in gold and silver.
Property wide rock geochemical surveys are planned for 2016 to be followed by drilling of select targets.
Regional and Local Setting
The new, Big Gold alteration zone lies near Jeff Kyba’s* “red line” (see map), an area said to be prospective for the discovery of new deposits. The line marks the contact between Triassic Stuhini and Jurassic Hazelton rocks and is near all of the major deposits presently being explored by Pretium Resources and Seabridge Gold within the Sulphurets region.
This area has opened up considerably in past years due to ongoing ablation (glacial meltback) and increased exploration activity.
On the Big Gold property rocks with green micas are present along zones trending northerly, occurring intermittingly along strike for hundreds of metres. Generally chrome micas, classed variously as fuchsite, mariposite and chromiferous muscovite, are commonly associated with gold-bearing districts of the Canadian Shield and have been noted in many other areas throughout the world. They have an intimiate association with ferruginous carbonate alteration zones and auriferous quartz veins, particularly in Canada. Chrome micas, much like sericite, have invariably been formed either by metasomatic processes or deposited directly with other minerals in veins. Minerals associated with them suggest they were formed under conditions ranging from moderate to fairly high temperature and pressure.
